PRESS FOR MOLDING FlRE-KiNDLlNG SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 281,923, dated July 24,182 3.

Application filed February 5, 1883. (No model.)

To a/JZ whom it may concern:

Be it known that I, THOMAS S. RAYNER, of Springfield, county of Clarke,State of Ohio, have invented a new and useful Improvement in Presses forMolding Fire-Kindling Substances, of which the following is aspecification.

My invention relates to that class of machines that are used for thepurpose of com- IO pressing and giving form to compounded kindlingsubstances.

The object of this invention is principally to simplify'the constructionof this class of machines, and thereby render their operation more I 5uniform, and at the same time more convenient.

In the'accompanying drawings, Figure l is a perspective 'view of amachine embodying my improvements. Fig. 2 is a perspective View of theplunger, represented as detached from the machine and with its bottomside up. Fig. 3 is a perspective view of the mold and its loose bottom.This is also shown as detached from the machine. Fig. 4 is alongitudinal section, representing the compressing -2 5 lever andplunger in proper position for compressing and giving form to thekindling substance in the aforesaid mold; and Fig. 5 is a similar view,illustrating the machine in a proper position for the removal of thekindling 0 after it has received the desired shape and solidity.

Similar letters indicate corresponding parts in each of the figures.

I have represented the machine as mounted 3 5 upon a rectangular stand,a, that is supported upon legs I).

-Upon the stand a, I erect a frame composed of the uprights c and e andconnecting crossbar d, for the reception of the plunger f and 40 mold g.

To the part (2 of the aforesaid frame I secure brackets h, that areprovided with guideways i, for the reception of the cross-head of thecompression-lever k. 5 The table a is provided with a rectilinear boardto form a yielding bottom, m, on which rests the mold, hereinafterdescribed, when the plunger is brought down. made yielding by elasticbearing-pieces p, so as to compensate for any uneven delivery of theplunger into the mold. To support the This bottom at is mold and yetpermit it to rock, I provide a ball-bearing at its center; but this isnot essential, as the elastic 'bearingpieces will of themselves providefor the proper yielding of 5 5- the bearing to compensate for unevendelivery of the plunger into the mold.

The plunger f is confined to its desired course of travel by means of aside guide, q, and studs 9" s, between which the projections t u, thatare .60 formed upon said plunger in a manner suit able for that purpose,are free to slide. The mold is supported by the auxiliary yieldingbottom m, and is held to place by being slid into grooves 11, formed inthe lower port-ions of the uprights c and c. This mold is composed of aloose bottom, w, transverse and 1011- gitudinal side boards, andvertical partitions 2, connecting the transverse boards, to provide aseries of longitudinal chambers, 10. The plunger f is constructed of anysuitable material, and is divided into sections 7 equal in number andcorresponding in configuration to the channels w, in which they h. ve towork. When the plunger f enters the mold g, thepar- 7 5 titions 2 passinto the gains a, and the knives b divide the kindling material, whichis in a semi-fluid state, into cakes of any desired shape, and thepunches 0 make diagonal perforations in the cakesone perforation to eachcake. After the cakes have been shaped and separated from the body ofmaterial from which they are formed, a sufficient time is allowed topass for them to set. Then the compression-1e- Ver is run back until itstwo pins Z enter the 8 5 holes Z, formed in the uprights f of theplunger, and said plunger is raised by the lever k until the projectionsa t on said plunger are at a suitable position to pass between the studsr s on the framing.- Then the plunger is moved 0 over bodily until itsprojections rest upon the projections 011 the framing. The mold 9 maynow be drawn out to the front of the stand, as shown in Fig. 5, and thecakes can be removed by lifting up the mold, which will leave the 5cakes upon the loose bottom 00.

It will be observed that the compressionlever 70 is capable 'ofadjustment in the slides This enables the operator to lift the plungerwithout raising the lever very much, and also permits of an increasedleverage when it is used in compressing the cakes into the mold.

I am aware that presses have been provided with molds having a slidingbottom combined with vertically-movable plungers for forcing the moldedblocks from the mold when the bottom of the latter is moved away; and Iam also aware that a gang of' cutters has been secured to a frameconnected with a pivoted lever, by which the frame is raised and loweredto cut and press material into cubes; but such features are not broadlyclaimed by me.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a machine for compressing and molding plastic kindling material,the combination of a frame-work having studs, a vertically-movableplunger, f, having projections at its ends, and means for engaging andraising the plunger to permit it to be moved laterally, to cause itsprojections to engage the studs on the framework and be therebysuspended, substantially as described.

2. The combination of the stand, the framework thereon, provided withstuds, the plunger arranged to rise and fall within the frame-work andhaving projections at its ends, the brackets carried by the frame-work,and the swinging lever for raising the plunger and permitting it to beadjusted laterally, to cause its projections to engage the lugs on theframe-work and be thereby suspended, substantially as described.

The combination of the frame-work having brackets 71, provided withguides 6, crosshead j having its ends arranged in guides, the lever 70,connected with the cross-head and provided with pins Z, and thevertically-movable plunger f, having holes Z, substantially asdescribed.

4. The combination of the frame-work and stand, the auxiliary bottom on,supported on the stand by yielding devices, the removable mold g, thevertically-movable plunger f, and the lever is, havings pins 1, forlifting the plunger, substantially as described.

5. In'a machine for molding and compressing kindling material, aplunger, f, subdivided into a series of plungers, so as to leave gainsa, and having knives b and punches c, in combination with a mold, 9,having partitions z and loose bottom a, substantially as an d for thepurpose described.

In testimony whereof I have hereunto set my hand this 1st day ofFebruary, 1883.
